SPECIFICATION forming part of Letters Patent No. 282,400, dated .my 31, 1883.

Application filed February 16, 1883. (No model.)

`RoNY STONEY, a subject of the Queen of Great Britain and Ireland, and residing at London, England, have invented an Improvement in Sluice or Flood Gates, (for which I `have obi tained British Letters Patent, dated September 10, 1874, No. 3,103,) of which` the following is a specification.

The object of my invention is to construct sluiees or nood-gates in an improved and simpliiied manner, so that the gates` may be operated with little power, and yet be durable and not easily put out of order.

My improvements are chiey intended for the drainage or relief of large rivers, reservoirs, andthe like; but are also applicable for regulating `or controlling the iioW' of any streams. My sluices are suitable for openings or passages of considerable Width-'for example, ifteen or thirty feet. Any number of them may be applied in the same channel to correspond to any required Water-Way.

The principal and distinguishing feature of my invention consists in an` arrangement whereby the pressure of the Water is entirely taken upon free sets of rollers traveling between vertical or nearly vertical rails on the back of the sluicegate and similar rails on the sluiceway.

In the accompanying drawings, Figure 1 is a vertical section on the line A B, Figs. 2 and 3; Fig. 2, a sectional plan on the line G D,

` Fig. 1;. Fig. 3, a vertical section on the line E F, Fig. 1, showing the gate closed; and Fig. 4, a vertical section on the line GI-I, Fig.

` l, but with the gate in an elevated position.

` The sluice-gate 5 is a strong vertical slide or shutter, represented as a framed wooden struct/ure, but which may be made of iron, or of iron and Wood combined. Thissluicegate 5 is fitted to Work in vertical grooves 6, formed for it in piers 7, or in the side Walls of the channel, and when closed has its bottom edge, y

8, in contact with the sill or bottom 9 of the opening, While 'its top edge then stands at high- Water or ood level. The sluice is opened by raising it, and the mechanism shown for raising it consists of vertical screw-sp'indles'lO, attached to. the vertical frame-pieces 11, which Patented in England September I, 1874, No. 3,103.

are lined to the projecting ends of the horizontal beams 12 of the gate, and are situated in. the grooves 6 of the pier oryside walls. ThescreW-'spindles 10 are tapped through the internally-screwed bosses of bevel-wheels 18, which have gearing With them bevel-pinions on horizontal shafts 14, arranged to be worked together by the same Winchehaudles 15.

The pressure of the water, which is in the direction shown by the arrows in Figs. 3 and 4, is entirely taken up by free sets of rollers 16, (the rollers being indicated by dotted circles in Figs. 3 and 4,) travelingbetween vertil cal rails 17, formed or Xed on the side frames,

11, of the sluice-gate, and similar rails, 1S,` fixed in the pier-grooves 6. Each set of rollers 16 is held in a frame consisting principally of a pair of plates, and suspended by a chain, 19, which passes under a pulley at the upper end of the roller-frame, and has ,its ends attached tothe upper parts, respectively, ofthe gate-rail 17 and 'of` the fixed rail 18 in each case.` In consequence of this arrangement therollerframes rise or fall half the distance moved through by the gate.

I am aware that anti-friction rollers mounted in bearings in the sluicegates have been used,

but I do not desire to claim anti-frictionl rollers generally in combination with sluicegates.

, I claim as my invention- 1." The combination of a sluice and sliding sluice-gate With free ,sets of rollers interposed and adapted to travel between the sluiceway and the edgesof the gate to sustain the pressure of the water on the gate, substantially as f and for the purpose set forth. p c

2. The combination of a sluice and sliding sluice-gate with `sets of rollers interposed between rails on the sluiceway and rails on the gate, and-a suspension-chain for the rollers connected to the gate and slniceway, substantially as describe y In testimony whereof Ihave signed my name to this speci tlcation in the presenceot two subscribing witnesses.
